                                    FORM OF
                                    -------


          OPTION EXERCISE, CANCELLATION AND EQUITY ROLLOVER AGREEMENT
          -----------------------------------------------------------

         AGREEMENT, dated as of January 19, 2000, by and among Stone Acquisition
Corp., an Ohio Corporation ("Sub"), Dayton Superior Corporation, an Ohio
Corporation (the "Company"), and the person identified on the signature page
hereto (the "Employee").

         Whereas, Sub and the Company have entered into that certain Agreement
and Plan of Merger dated as of January 19, 2000, (as such agreement may be
amended from time to time, the "Merger Agreement"; capitalized terms used but
not defined herein shall have the meanings set forth in the Merger Agreement)
pursuant to which (and subject to the terms and conditions specified therein)
Sub will be merged with and into the Company (the "Merger").

         NOW, THEREFORE, in consideration of the mutual covenants herein
contained and other good and valuable consideration, receipt of which is hereby
acknowledged, the parties hereto do hereby agree as follows:

         The Employee hereby affirms and represents and warrants that as of the
date hereof he or she (i) is the record and beneficial owner of that number of
shares of Class A common shares of the Company, without par value (the "Common
Stock"), as specified on Exhibit A attached hereto under the heading "Cash
Buyout," (the "Buyout Shares"), and that number of shares specified under the
heading "Equity Rollover" on Exhibit A (the "Rollover Shares" and collectively
with the Buyout Shares, the "Prior Shares"), and he or she is the holder of the
options to purchase shares of Common Stock (the "Options") of the type (ISO or
NQSO), and for the number of shares and exercise price as specified on Exhibit
A, (ii) owns or holds no other Equity Securities of the Company or any of its
Subsidiaries and (iii) has sole power of disposition with respect to the Prior
Shares and the Options and will have sole power of disposition with respect to
the shares of Common Stock acquired upon the exercise of the Exercised Options
(as hereinafter defined) (the "Acquired Shares") and the Series A Shares.

         The Employee hereby consents, covenants and agrees that (i) prior to
the Effective Time, he or she will exercise those Options, if any, identified on
Exhibit A under the heading "Required Option Exercise" and will exercise such
additional Options as may after the date hereof be identified by Sub
(collectively, the "Exercised Options"); (ii) he or she will vote all Prior
Shares, all Acquired Shares, all shares of Common Stock hereafter acquired by
any means (including, without limitation, by exercise of Options) (the
"Additional Acquired Shares") and all Series A Shares (to the extent the vote of
the Series A Shares is necessary to approve the Merger and the adoption of the
Merger Agreement) in favor of, and raise no objections to, the Merger and the
adoption of the Merger Agreement and the other transactions contemplated by the
Merger Agreement and waive any rights of appraisal; (iii) prior to the Effective
Time, all Prior Shares (other than those, if any, specified under the heading
"Cash Buyout" on Exhibit A) and all Acquired Shares will be exchanged for a like
number of shares of Series A Shares as contemplated by Section 6.12 of the
Merger Agreement and at the Effective Time, by virtue of the Merger and without
any action on the part of the Employee, each Series A Share outstanding

immediately prior to the Effective Time shall automatically be converted into
the right to receive one Surviving Corporation Common Share.

         The Employee further consents, covenants and agrees that (i) certain
Options (other than Exercised Options) that remain outstanding as of the
Effective Time (the "Non-Exercised Options") may be eligible to be cancelled on
the Effective Time in exchange for payment as described in the Merger Agreement;
[(ii) the Employee and Sub will mutually identify prior to the Effective Time
those Non-Exercised Options that will not be cancelled (the "Retained Options");
provided, however, that unless otherwise approved in writing by Sub prior to the
Effective Time, the aggregate "Net Value" (as hereinafter defined) of the
Retained Options PLUS the Net Value of the Rollover Shares and the Net Value of
the Acquired Shares will not be less than the amount set forth on Exhibit A as
the aggregate "Net Value Rolled" (for purposes of this Agreement, "Net Value"
with respect to an Option means the excess of (x) the product of $27.00 and the
number of shares of Common Stock covered by such Option over (y) the aggregate
exercise price of such Option; with respect to a Rollover Share means $27; and
with respect to an Acquired Share means $27 MINUS the exercise price thereof)
[(it being understood that the retention of the Retained Options is a condition
to the Employee's receipt of any amount pursuant to Section 3.3 of the Merger
Agreement)]; (iii) Retained Options will either remain outstanding following the
Effective Time or be replaced with options to purchase shares of Surviving
Corporation Common Shares intended to provide the Employee with benefits and
economic value comparable to the Retained Options] and (iv) he or she will
execute such other documents and take such actions as may be requested by Sub in
order to carry out the terms of this Agreement and will not take any actions or
authorize any Person to take any actions which would be inconsistent with the
terms of this Agreement.

         Notwithstanding anything to the contrary herein, the Employee further
consents, covenants and agrees that all Prior Shares (other than those exchanged
for Cash Merger Consideration in accordance with this Agreement and Section 3.4
of the Merger Agreement), all Acquired Shares, and all Retained Options (and the
shares of Common Stock or Surviving Corporation Common Shares subject to
purchase upon exercise thereof) will be subject to the [Management] Stockholders
Agreement, which will contain provisions regarding transfer restrictions,
tag-along all drag-along rights, and put and call features applicable to shares,
as well as other customary terms and provisions.

         The Employee understands and agrees that this agreement shall be
binding upon the Employee, his or her successors, assigns, heirs, administrators
and executors without regard to whether the Employee is employed by the Company
(or any of its Subsidiaries) as of the Effective Time. This agreement shall
become void if the Merger Agreement is terminated.

         The Employee further agrees that a breach by him or her of his
covenants hereunder will cause irreparable injury to the Sub, that the Sub has
no adequate remedy at law with respect to such breach and, as a consequence, the
Employee agrees that each such covenant shall be specifically enforceable
against the Employee, and the Employee hereby waives and agrees not to assert
any defenses against an action for specific performance.

         The Company hereby consents and agrees (i) if requested by the
Employee, concurrently with the exercise of the Exercised Options the Company
will lend to the Employee in the form of


                                       2

a [non-interest bearing], recourse promissory note payable by the Employee to
the Company and secured by a pledge to the Company of the Acquired Shares the
principal amount requested by the Employee which shall not be greater than [the
sum of] the aggregate exercise price of the Exercised Options [and the aggregate
estimated federal and state income tax liabilities payable by the Employee upon
such exercise as set forth on Exhibit A]; and (ii) to take such actions as are
necessary to carry out the terms of this Agreement.
